Abstract (en)

[origin: WO8903826A1] A new class of sulfonated 2-(2'-hydroxyaryl)-2H-benzotriazole compounds and method for using them and other sulfonated hydroxyaryl benzotriazoles on nylon fibers to improve stain resistance and dye lightfastness has been discovered. A process is provided for improving stain resistance of nylon fibers by treatment with sulfonated aromatic-formaldehyde condensate and fluorinated dry soil resist agents.
